Setup

Initial Setup

# Sync dependencies from uv.lock (creates virtual environment automatically)
uv sync

# Alternatively, activate the virtual environment manually
source .venv/bin/activate  # Linux/Mac
# or
.venv\Scripts\activate     # Windows

Environment Variables

export PAAPI_ACCESS_KEY="your-access-key"
export PAAPI_SECRET_KEY="your-secret-key"
export PAAPI_PARTNER_TAG="your-partner-tag"
export PAAPI_HOST="webservices.amazon.de"       # optional defaults to webservices.amazon.de
export PAAPI_REGION="eu-west-1"                 # optional defaults to eu-west-1
export PAAPI_MARKETPLACE="www.amazon.de"        # optional, defaults to www.amazon.de

Testing

Run the simple test suite:

# Run all tests with uv (recommended)
uv run python -m pytest test/test_service.py -v

# Or if you have activated the virtual environment
pytest test/test_service.py -v

The test suite includes:

• Service initialization tests
• Configuration management tests
• Search functionality tests with mocking
• Error handling tests

Usage

from service import AmazonPAAPIService

# Create service (uses environment variables)
service = AmazonPAAPIService()

# Search for items
items = service.search_items("echo dot", "Electronics", 5)

Running the MCP Server

# Run directly with uv (recommended)
uv run python server.py

# Or if you have activated the virtual environment
python server.py
